Hello Jingchen,
This is correct, the Sicer tool has the supported genomes hardcoded in
by the tool authors. These are (not all are the same as Galaxy
"database" names):
'mm8', 'mm9', 'hg18', 'hg19', 'dm2', 'dm3', 'sacCer1', 'pombe', 'rn4',
'tair8'
To ask about adding more genomes, you could try contacting the tool
authors here through their google group:
http://home.gwu.edu/~wpeng/Software.htm
I asked and our team was unaware of any updates, but if there was one,
the tool authors could submit to the Took Shed and and/or create a
development ticket as appropriate.
Hopefully this helps to clarify and point you in the right direction,
Jen
Galaxy team
